With her jaw-dropping 34-second knockout of Bethe Correira last week, Ronda Rousey once again established herself as one of sports world's the most dominant fighters.

But while her performances in the ring are often over in less than a minute, Rousey has been engaged in a different kind of combat for several weeks now, and her opponent clearly has no intention of throwing in the towel.

Floyd Mayweather may have pulled in a massive payday for his ultra-hyped (and ultra-boring) fight against Manny Pacquiao, but he may soon be forced to hand over a sizable chunk of his earnings to the mother of three of his children.
